Recipe Notes

  • Variations: Try tuna, salmon, or codfish steaks instead of the swordfish. Fillets will also be good in this recipe, but cut down on the cooking time. Be sure the potatoes still cook for 25 minutes. Just put the fish in later.
  • Wine Recommendation: Though not a typical Italian wine, pinot noir is superb with swordfish. There are some tasty pinot noirs from the Alto Adige and Friuli, which can be found under the Italian name pinot nero.
